IMPROVEMENT IN MINE RS FUSE-LOCKS.
Specification forming part of Letters Patent No. 58,639, dated October 9, 1866.
To all whom it may concern:
Be it known thatI, GEBHARD HAGENMEYER, of Big River, in the county of Mendocino and State of California, have invented a new and useful Improvement in Miners Fuse-Locks; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is an elevation of a longitudinal section of a fuse-lock made according to my invention, the section being taken on the line as of Fig. 2. Fig. 2 is a plan thereof when ready to be operated.
The object of this invention is to provide an apparatus, by means of which miners and others can light a fuse with safety to themselves and with certainty.
It consists of a lock having a barrel to receive the end of a fuse, and anipple to receive a percussion-cap. When the lock is set the apparatus is thereby fastened to the fuse. The hammer is made to strike the cap by means. of a cord or wire, and the lock is released from the fuse by the falling of the hammer, so that it maybe drawn away by means of the cord from the scene of the explosion.
at designates the body of the apparatus. It has an opening, b, in it, which extends from its rear end nearly to its front end, where it cpmrgunicates with the perforation of a nip- P I To the back part of the body a of the look a hammer, c, is pivoted at 6 between standards h k, that rise on either side of the barrel 1) at that end. The upper side of the barrel is cut away between the standards h h, so that the back part of the barrel is covered by the free end of a flat spring, 6, whose elasticity is exerted constantly against the tail end of the hammer c.
The hammer carries on its end between the standards a friction-roll, j, which is in contact with the spring when the hammer is raised.
The spring 0 lies on the top of the barrel, and is connected to the apparatus by means of an eye on its upper end, which is passed over the nipple and afterward secured thereon by a ring or nut.
To the front part of the body a in front of the nipple is hinged a scar or dog, 9, whose upper end fits into a notch on the front end of the hammer when the latter is raised, and so holds it up above the nipple.
A hole, It, in the sear near its top enables the operator to secure a cord or wire to the apparatus, by means of which not only can the sear be drawn from beneath the hammer to explode the cap, but also the apparatus itself be pulled away from the neighborhood of the blast to preserve it from possible injury.
The end of the spring on its under side has a sharp pin, j, which projects downward into the barrel 1), so as to take hold of and pierce the fuse when the hammer is raised, at which time the tail end of the hammer presses downward on the end of thespring and forces its hook j into the barrel.
The way the apparatus is used is as follows: When a fuse is to be lighted the lock is connected to the fuse by inserting the fuse in the opening or barrel 1). The hammer is then raised and the sear g placed under the face of the hammer. The tail end of the hammer presses on the spring and forces its pin j into the fuse, and holds the latter fast and prevents it from becoming accidentally detached. A percussion-cap is next placed on the nipple, and a cord or wire fixed in the hole 70 of the sear is carried to a safe distance from which it may be pulled, so as to remove the sear from under the hammer, when the latter will fall, being aided in its descent by the spring 0, and will explode the cap, and so light the fuse in the barrel. The falling of the hammer releases the fuse from the pin j, and the operator then draws the look away from the place, so that it may not be injured or lost.
The seal 9 may be forced toward the lock by a spring, so as to insure its engagement 2. The pinj, in combination with the spring With the hammer automatically when the lat- 6, when used for the purpose herein repreter is raised. sented and described.
I claim as new and desire to secure by Letters Patent- GEBHARD HAGENMEYER.
1. As an improved fuse-lock, the arrangement of the hammer 0, sear or dog g, spring \Vitnesses:
